The Zipp 303 Firecrest Carbon Clincher Disc Front takes road bikes where they’ve never gone before, lets them do more, and be ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp® 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With an all-new disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever.

The 45mm deep 303 Firecrest delivers unmatched aero performance when used with the wide tires that today’s riding demands. We’ve achieved this with a wide disc-specific rim design featuring ABLC dimples extending all the way to the outer edge of the rim. In addition to achieving AeroBalance™, the industry leading crosswind stability and low aerodynamic drag that defines all Firecrest wheels, the new 303 Firecrest delivers lower drag than the outgoing version when used with 25c or wider tires. The aerodynamic performance gap between a narrower rim and the new 303 grows even larger with 28c and wider tires thanks to a smoother transition between the tire’s profile and our new rim shape. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. Setup tubeless and emblazoned with your choice of six color decal options at the factory, 303 Firecrest wheels are as alluring as they are easy to use. And should you choose to run tubed tires, the new 303 is also fully compatible.

And like all Zipp carbon wheels, the new 303 Firecrest is laid up, molded, drilled and assembled in Indianapolis, USA. Built to take you to places you’ve never been, the Zipp 303 Firecrest Carbon Clincher Disc Front wheel will go the distance, faster.
